wire from coils of the same and cut it olf after being straightened in predetermined One such machine is disclosed in U. S. Patent #1,466,334, dated August 28, 1923, entitled Machine for cutting and. swaging bale ties, and issued to A. J. Gerrard, et al. This invention proposes to utilize to some extent the mechanism of the above-mentioned patented machine and to add thereto the other'parts which are especially adapted for heading the tie wires after they have been straightened and cut. rlhe principal parts of the above mentioned machine which are utilized in the present invention are diagrammatically illustrated in dotted lines on the drawings while the parts that are added to such machine `appear in full lines.

lt is-not deemed necessary to go into the operation of said patented machine in detail, and therefore the following description will treat the prior construction in ageneral way and will be more detailed when it describes the construction of this im- ,provement Referring morey particularlyto Figs. 1. and 2 of the drawings,*1 indicates the coil j'of wire, 2 indicates the straightened wire, 3 indicates a pulley operated from/ a belt 4 passing around the power pulley 5 mounted on the power shaft 6, provided with the power' pulley 7, around which., passes the power belt 8, and 9 indicates a bevel gear on the power shaft 6 meshing with the bevel gear 1Q rigid with the shaft 11, carrying the grooved guide pulley 12, while 13 indicates a well known form of wire straightening device. All of the foregoing parts are or may bethefsame as in the abovementioned prior patent. In said prior patent, however, the wire 2 passes along the ,guide member 14 untilit strikes an adjustable obstruction indicated at 15, and which is more' plainly shown at v43'in Fig. 1 of said prior patent. This said obstruction 15 is connected with the member 16 which is vprovided with the actuating rod 17 connected as at 18 to the bell crank lever 19 pivoted asat 30, and connected as at 21 to the rod 22, connected as at 23 to the clutch controlling device 24, which cuts in and cuts out the power from shaft 6 to the cam member 26 which actuates the roller 27 mounted on the cutting bar 28 carrying the cutter indicated at 29, Fig. 1. 25 indicates a fly wheel mounted on the shaft Gand 125 indicates the framework, all as will be clear from said prior patent.

' The power shaft 6 terminates at the point 30, Fig. 1, and in line with said shaft is another Apower shaft 31 provided with the Acollar 32l rigid with' said shaft 3'1, as bestshown in Figs. 1, 7, 8, 9, 10 and 11. Said fly wheel 25 is provided with a hub33 carrying the pins 34 and said collar 32 is provided with a slidable pin 35 having a right angular extension 36 provided with a beveled end 37 all as 4will be clear from Figs. 7, 8 and 9. -Coacting with the sur- 1 face 37 is the vertically disposed member 38 provided at its lower end with a similar beveled surface 39 adapted to wedge in between the extension 36 and the collar 32, and to thereby slide ythe pin 35 'longitudinally of the shaft 31.k Said pin 35 is controlled by the coiled spring 40, see Figs. 8 and 9, and in its normal position the extreme end of p`in`35 liesin the path of the pins 34, so that power will normally be transmitted from the shaft 6, to the fly wheel 25, to the pins 34, to the pin 35 to the collar 32,l and to the shaft 31.

As best shown in Fig. 10, the vertically disposed member 38 passes up through the member 41 of the frame and also through the member 42 of the frame and is provided with the enlarged head 43, as shown. The extreme upper end of the head 43 is provided with a roller 44, and through said head also passes the `shaft 45 on which is mounted the cam 46, as shown. A spring 47 attached to the member 38 as at 48land tothe frame 41 as at 49, controls in one direction, the movement of the member 38. A s best` shown in Figs. 2, 3 and 10, a wedge member 50 is adapted to reciprocate undernneath the edge 51 of the extension 43, and

thus raise thermember 38 against the action of the spring 4.7 while said spring moves said member38 in a downward direction after the wedge 50 has recveded. The wedge 50 is .carried by the eXtreme end of the lever 52 pivoted, as at 53, and actuated by the above mentioned cutting lever28, all as will be clear from Figs. 1, 2, 3, 4 and 10.

It thus results from the mechanism thusv far disclosed that as the wire 2 isi pushed along the guide 14 and actuates the member 15 to push longitudinally the rodv 17, thebell crank 19` is actuated to vertically lift the rod V32 and to operate the clutch with which the cam 26 is associated. and thus cause the power from shaft 6 to rotate said cam 26,

all as is disclosedin said Patent*#1,466,334, above mentioned. The rotationof the cam 26, see Figs. 1, 2 and 4, actuates the lower end of the cutting `lever 28 which is pivoted as at 54 and serves to cut olf the wire 2at the point 55, see Fig. 4. The actuation of said lever 28 causes it to contact with the end 56 of the lever 52 and to turn said lever on its pivot 53, Fig. 2, which`\\forces the wedge shaped end 50 underneath the edge 51 the collar 32 to transmit power from the shaft 6 to the shaft 31, each time a given hlength of wire is cut off at the, pointj55,

' mounted a sprocket 60 around which said chain 58 ,also passes. Rigid with the' Asprocket 60'is the gear 61 meshing with the is another `vlever 72 associated with anotherV i is also provided with gear 62 mounted on t-he shaft 45 and serving to turn said shaft, all as will be clear from Fig. 1 of the drawings. Mounted on the left hand end of the shaft'45 is a gear 63 meshing with the gear 64 mounted on the stud shaft 65, Fig. 4. Rigid` with the gear 64 is the disc or cam' shaped member 66 having the depression 67 in its periphery. Said stud shaft 65 is carried bythe frame member 68 of the frame and on said member 68 is mounted the shaft I69 carrying the lever 70 rigid therewith and provided with the projection 71 adapted to ride on the pe-` riphery of the disc 66, and.,to fall into the notch 67 at each revolutionof said' disc. Said lever 70 is also provided at its eXtreme lower end with thehook member/74.,'Re ferring more particularly to Figs. 1 and 27, it will be observed that on theright .hand end of the shaft 69, asseen in Fig. 1, vthere vertical member 73*I forming a part of the frame of the machine. Said other lever 72 a hook-like projection 75, as shown. i

From the foregoing description, it, will now be clear that as the power from'the shaft 31'is transmitted through the sprockets,

57 and 60, through the gears Gland 62, through the shaft 45 and the gears 63 vand 64, the disc 66 will be'rotated,'and the projection 71 willfall into thenotch 67, thus moving the hook-like projection 74 carried by the lever 70 in a counter clockwise direction, as seen in Fig. 4. Asl said lever is rigid with the shaft 69, the turning of the same will likewise turn the companion lever 72, see Fig. 2, and its hooked end 75 in a clockwise direction. The parts are so timed that when a wire 2 is cut at the point 55, it

' will roll down the edges 76 of the end frame members 6 8 and 73, until it strikes the hook projections 74 and 75 carried `by the levers and 72, respectively, whereupon immediately another wire is fed out of the straightening machine at the point 55. While this said second wire is .being fed out of the machine, the first-mentioned wire is'held in the -position shown in Fig. A4, but just before said second wire is cut at point 55,-the projection 71 falls into the notch 67 and said wire 2 is allowed to fall into a'space 77 located between thetfender or member- 78 of the frame and the member 79 thereof. Said described.

wire 2 then occupies the positionindicated at 80, Figs. 4 and 29.

In the meantime' the continued rotation of the disc 66 forces the projection 71 out of the notch 67 and restores the levers 70 and 72 back to the positions shown in Figs. 4

and 27, respectively. When the levers return to theie last-named positions, the second wire falls down the edges 76 of the frame members 68 and 73, and occupies the position on the hooked ends 74 and 75 of .the levers v70 and 72, indicated in Fig. 4

The 'frame or fender member 78, Fig. 4, is provided with `a bracket or projection 83 against which the hook 74 of the lever 70,

.contacts and thus prevents .the said hook 74 from moving too far, andv it further closes The heading or 'constructed and operated as follows Referring first to Fig. 20, Sheet 7 ,j there is rigidly mounted on the shaft 45, thesegmental beveled gear 90 meshing with the bevel pinion or gear 91 rigid on the knotting Yshaft or member 92:T On the right hand end of the knotting member 92, as' seen-in Fig. 20, there is. rigidly attached the collar 93 and beyond said collar the slide able member 94 is disposed. TheZ knetter knotting mechanism is shaft 92 rotates in said slidable member 94,

as will presently appear. Said collar -93 contacts with the 'smaller end surface of the bevelpinion or gear 91 land rigid with the said gear 91' is the rectangular bloek95., To the `left of saidblock 95, as seen inFig. 20, is another poftion 96 of theslidable member 94. 97 indicates a portion of the frame constituting a housing for the parts just mentioned. As best-shown in Fig. 15,

ythe end frame member 73gof thevmachine is beveled as at 98 and 'is also thickened as indicated. This thickened portion 98 is cut away as shown to accommodate the sliding block 94 which slides upon the rails 100 and 101. A strap 102 (see Figs. 13, 14, 15,

18, and 22) serves to ,hold the left hand porl tion of the knetter 92 in position to rotate in the said slidable block 94. A similar strap 103 holds theextreme right hand end of the knotter92 in position as indicated in Fig. 22. Attached to"the slidable block 94, as best shown in Figs. 12 andv 20, are facing plates 104 and 105 made of hardened steel. The facing plate 104 is cut away to form 107 as indicated in Fig. 22. The said surfaces 106 and 107 are not struck from the same centers as will be clear from Fig. 12, so that the pin 108 carried by the shaft 45,

as it contacts with said surfaces recipro-A cates the block 94 to the right and left as seen in Figs. 20 and 22.

It will be clear from the mechanism thus far described that as the pin 108 makes a complete revolution the knotting member 92 with its yassociated parts will reciprocate toward the right and left, as seen in Figs. 20 and 22, and the bevel gear pinion 91 will be intermittently disengaged from the Segmental bevel gear 90 and re-engaged therewith for a purpose to be presently described. That is to say, the parts will be reciprocated from the position shown in Fig. 20 to the position shown in Figs. 12 and 13V, whereupon the eXtreme end portion 110 of the knotter will project out beyond the lframe portion 97 as indicated in said Fig.

12, While the segmental gear 90 will have moved its gear teeth through an angle of about 180 from the position shown in Fig. 20. When moving to its extreme left hand position, shown in Fig. 12, the teeth of the pinion 91 of course are disengaged from the teeth of the segmental* gear 90 as above stated, and When they are to be re-engaged,

there is some danger of the two sets of teeth not inter-meshing properly unless said danger is avoided. n

To insure the proper engagement of these two sets of teeth, there is provided the abovementioned rectangular plate 95, whichis rigidly attached to the knotter member' 92 and rotates therewith. That is to say,` said plate 95 being rigid with the pinion 91, the

'A pin 108 after traveling through an arc of 90 in the direction of the arrow, Fig. 12,

begins to move said pinion 91 and plate 95 from Athe position shown in Fig. 12, toward the right as seen in said figure. At lthe same timefthe segmental gear 90 Will turn in a counter-clockwise direction as seen in Fig. 12, and the teeth 130 of said gear 90 will therefore approach the teeth of said pinion 91 as will be readily understood. Therefore, to insure said proper re-engagement of said teeth, as above mentioned, the gear/62 is provided with a cam 131, Fig. 20, which hasv an inclined surface 132 which takes under4 the edge 133 of the plate 95, see dotted lines ir Fig. 20. The parts are so proportioned that the engagement yof the surface 132 with the edge 133 has the elect of rotating the plate 95 and pinion-91 to such positions as will insure the engagement of the teeth of the pinion 91 and of the segmental gear 90, all as will be readily understood.

From what has been so far disclosed, it

willl now be clear that as. the clutch consisting of the members 32 and 34, Fig. 1,

performed on the Wire 2 and more or less ltension or spring action will be generated in said Wire. In the meantime, the pin 108 will begin to move the knotter shaft. 92 and its associated parts toward the left, as seen in Fig. 20, and thus to4 separate the teeth of the gear 90 from the teeth of the pinion 91. After this separation takes place, the lrnotter shaft 92 together with pinion 91 and their associated parts will be turned backward through an arc of 90 or through one quarter turn by reason of the plate 95 taking againstthe curved surfaee'115,'all as will 'be presently referred to. The ypin 108 will neXt move the parts back -tward the right as seen in Fig. 12, and as the parts associated with the pinion 91 have been turned through an angle ofy one and a quarter-turns, and have beenl turned by the plate 95 in an opposite direction through at least a `quarter of a turn, the said pinion teeth and its associated parts are liable'to have vbeen moved out of their lproper angular vsaid plate a'nd pinion 91 into thev proper angularposition to insure the engagement of the teeth of said pinion with the'teeth of the segment 90. The dwell 134 associated with the cam 131 still further serves to positively hold the teeth of the pinion 91 in the proper desired angular position. p i

On the other hand, the said spring action that has been generated in the Wire 2 may turn the plate 95 and the teeth of the pinion 91 Vin a direction opposite to that in which the cam 132`Would act tox counteract said turning. Insuch case, the cam 135 and its associated parts 136 and 137, see Figs. 15 and 19, will come into action and turn the teeth of the pinion 91 through contact with the plate 95 intol the proper positioutov insure'that they willl re-en'gage with lthe -teeth of the cam 90. That is', said cam 135,

sides of the plate 95 and so hold the saidplate from further revolution about .the member 92 as a center. 'lhe cam 135 is suilicient inA length to hold the said plate 95 in the correct position until pin 108 in its continued movement takes againstvits bearing plate 105 and starts the movement of the member 92 and its associatedparts towards the left., as seen in Fig. 22.

The pinion 91 and plate 95 are turned back through the above mentioned angle of 90o as follows z-As best illustrated in Figs.

'12 and 20, there is loosely attached to the trame member 97 the toe plate member 111 'Y 4and 75. rllhe wire 2 thus released from the as by the bolt and pin connections 112. A spring controlled member 113, see Figs. 13 and 20, controls the position of said\plate relative to its pivot 112. lt will be further observed from the said-figures, that said plate 111 is provided with the inclined or beveled portion 115, see Fig. 22, which starts at the point 116 and which is opposite the lower edge 117 oi the plate 95.

is the pin 108 shoves the plate 95 toward the lett, as seen in Fig. 22, said corner 117 strikes the portion 116 of the incline 115 and rides up along the curve or incline 115, as will be clear from Fig. 20, whereupon the pressure on the plate 95 exerted by the ineline 115 will rotate said plate 95 around the axis oit the knetter member 92 as the center. rlhis rotation will extend through an are of one quarter turn or of 90, while the plate 95 is moving toward the, left, as seen in Figs. 20 and 22. ln order to permit the plate 95 to rotate through this said are and in the manner described, the frame member 73 is cut away as at 120, see'Figs. 18 and 20.

The pin 108 in its continued revolution, see 12, will take against the projecting corner otl the plate 104 and move the same together with the knotter member or shaft 92 and its associated parts to the right as seen in saidL figure. ln so doing, see Figs. 15, 18 and 22, the lower corner 117 of the square plate 95 will strike the beveled portion 140 et the plate 111. How ever, the plate 111 will give against the compression ol' the spring of the .member 113 and thus allow the plate 95 to snap past the said plate 111; During this operation, the plate 95 may, however,

become canted, or the said plate 95 and the'pinion 91 rigid therewith may move out 01 the proper engaging position with the segmental gear 90 dueto the spring action of the said. wire 2 above mentioned, but as previously described, the cam 131 carried by the gear 62 willy come into position at ythe proper time and right' the plate 95 so that the pinion 91 will be positively positioned to mesh with the teeth 130 of the segmental gear, as disclosed above.

It will now be clear that the parts of the mechanism are so positioned and timed that when a wire 2, Fig. 1, has been released from the hooks 74-and 75, see Figs. 4 andl 12, and is dropping down into the space 77,

vanother wire 2. has been fed from the kstraightening mechanism through the point 55, and cut oil by the cutting member, and

`has dropped onto the inclined surfaces 76 of the frame members 68 and 73 of the machine. But the hooks `74 and 7 5 after releasing the wire 2 held thereby are repositioned against the brackets 83 andV 85 before the newly cut wire 2 has fallen down the inclines 76 to said. hook members 74 hooks falls down through the space 77, -into theposition shown at 80, and one end of the said wire rests on the holding arm 81, see Figs. 4 and 5. |This holding arm 81, is pivoted eccentrically at 141 to one end of the shaft 45. rlhe other end of arm 81 projects through the plate 79, see Figs. 2, 4 and 5, so as to support the wire l2..

llhe other end ot the wire 2 is supported by an [L -shaped member 145, Figs. 27 and 28, Sheet 2 pivoted as at 146 to the supporting plate or frame member 73. One end 147 of this member 145 is engaged by a cam 148 mounted upon the shalt 45, as clearly shown insaid Figs.y 27 and 28. rlhe other end of the member 145 is provided with the right angled extension 149 and the notch 150 adjacent thereto, and adapted to receive the wire 2. yl`hus, it will be seen, Figs. 5 and 27, that as the shaft 45 revolves in the direction indicated by the arrows, the supporting latch member 81 will be reciprocated backwards and forwards in such a manner that when the said member 81 is in the eXtreme lett position, the held wire 2 will be released :rnd allowed to fall. With particular reference to Fig. 27, it will be noticed that-as the shaft 45 revolves the end-147 of the supporting member 145 will ride the periphery of the cam 148, thus holding the end oi the wire in the note'ii 150. The member 145 is so positioned on the trame 73 that the notch 150 therein is in the samehorizontal plane with the head 110 of the'knotter shaft 92 when the end 147 of the said member 145 is riding the periphery of the vcam 148. But, during the knotting or twisting operation, the end 147 takes into the notch 151 of the cam 148and allows the notch150, as well as the extension 149, to drop under the-action of gravity from its wire holding position and thus allows said wireto be held in the notch or groove 158 ot the knotter head110, asM will bel more fully disclosed below.

The operation ofthe mechanism, so far 'I member 29, drops1 onto the inclines 76 of the trame members 68 and 73. 1n sliding down these inelines, the extremities of the wire 2 contact against the guiding plates 155 and 156, see Figs. 1 and 29, so that one end of each wire will be positioned at a uniform distance from the knetter head 110 and will be headed at a uniform distance from the other end thereof. 'llhat is, the wire 2 having been released by the holding hooks 74 and 75, now drops upon the supporting arms 81 and 145, placing it in the position shown at 80, see Figs. 1, v16, 27, 13, 20 and 29. lln this position, it will be seen that the extreme end portion 157 of the wire will be positioned in the transverse groove or slot 158 of the knetter head 11G, see especially Figs. 12, 13 and 39. This-knotter head in addition to this transverse groove 158, is provided with the longitudinal and parallel side grooves 159 and 169 on either side of the upstanding portion 161. These grooves 159 and 160 are ot sullicient size to take the wire when the knetter head 110 is withdrawn into the machine. rFhat is to say, these said grooves 159 and 160 are of a width equal to the diameter of the wire 2. lt will be noted7 see Figs. 16 and 30, that the member 161 of the knetter head is not strictly rectangular but is slightly hook shaped in transverse section, the top portion bending over toward the rightq as seen in Fig. 16, lor a purpose which will be disclosed below.

As pin 168 in its circular movement, see Figs. 12 and 13, contacts with the plate 104 and moves the same toward lthe right, as seen in said igures, the head 110 or the knetter mechanism will be drawn into the machine carrying therewith a portion et the end 157 olf the wire. ln so doing, however, the wire will be bent and provided with a transverse itl-shaped bend 170 as clearly indicated in Fig. 14. lJVhen the pin 108 has advanced the knotting mechanism to its fullest extent toward the right, as seen in Figs. 12 and 13, or in other words when the pinion 91 has been drawn into mesh' with the teeth 139 of the segmental gear 90, rotation of the knetter shaft 92 and its associated parts will commence. From `Figs. 14, 20, 22, 23, and 24, it will be seen that as the pinion 91 is revolved by the gear 90, the main body portion 162 of the wire 2 will be wrapped around the transversely extending end portion 157 of the said wire, and alter 'the full one and one quarter turns ot the said pinion 91 have taken place, there will have been formed the looped knotted end 165, see Fig. 21, on the wire 2.

'lhe segmental Igear 96 having now revolved the pinion 91 to torni this twisted loop, the pin 198 takes against the plate 105 in its continued revolution, thereby pushing the knetter shaft 92 and its associated parts toward the left as seen in Figs. 12, 13,

2O and 22. During the outward movement of these parts, shaft 45 has turned the cam 148, Fig. 27, to that position which allows the end 147 of lever` 145l to engage the notch 151 of said cam, thereby allowing the holding lever 145 to turn about pivot 146 as a center and thereby lower the angular extension 149 of said lever to the( position shown in Figs. 22 and 25. lin other words, the portion 149 has been lowered out of the position 80 of the wire v2, whilefthe looped knotted end 165 is being ted out of the machine, so that the headed wire may be released from the knetter or twister head 110 and allowed to drop therefrom,

lt will be noted particularly from Figs. 19 and 25, that at the completion et the twisting or heading operation and while the knetter shaft 92 and its associated arts are moving to the left,'as seen in sai figures, the main body portion 162 of the wire is moved outwardly from the position it occupies in Fig. 20 to that shown in Fig. 19,thus being cleared from the holding lever 145.

lll/'hen the pinion 91 has been rotated its full one and one quarter turns, as heretofore described, the wire 2'will be in the position as shown in Figs 22 and 23. Upon the turning back of the pinion 91 by reason of the plate riding the incline 115 or the plate 111, the wire 2 will be put under a strain and bowed into the shape shown in Figs. 24 and 29, imparting a tendency therein to spring from such position. 'Upon the further backward turning of the knetter shaft 92 and its associated parts, see,x 24, 25 and 26, inthe direction of the arrws. the loop 165 will slip ott the hook shaped upstanding portion 161 of the knotter head and spring lfrom the position maintained during the twisting operation, thus allowing the now completely headed wire te tall to the weighing mechanism with which this machine is provided, and which will now be described.

lll

The weighing mechanism with which lthis and secured in adjusted position, as by the screws 177, see 3. The forward ends of the levers 175 are provided with the yokes 178 pivoted, as at 179, to said levers..4

lhe plate 42 is provided with depending lingers 180 to which is secured one end ott a lll l spring 181, the other end of which is secured to the yoke 178, as at 182. rlhe yoke 178 is enlarged as at 185 on one side of the pivots 179, and one of the prongs of the yoke 178 extends upwardly as shown in Fig-6, at 186, to take against the flange 187 of the plate 42. This weighing mechanism is of the usual well known type in machines of this character and should be readily understood from the foregoing description. A brief description of its operation, however, is as follows The wires 2, after having been provided with the looped head or tie 165, as heretofore described, upon leaving the knotter head 110, will fall under the action of gravity into the weighing yokes 178. Here,

they will collect until a sufficient quantity v thereof will overcome the weight of the adjustable. sliding weight 176 vlocated on the rearwardly extending portions of the balancing levers 175, whereupon the load of wires 2 carried by the yokes will cause the levers 175 to tilt about the points 172 as a center. rlhe pivot 179 of the yokes 178 are so positioned that upon the tilting of these weighing levers 175, the weight of the wires 2 in said yokes will overcome the weight of the enlargedportion 185 of the yokes, causing the yokes to turn about the pivots 179 as a center, and allow the accumulated wires 2 to be spilled from the yokes 178 into any suitable collecting means such as the hooks 190, see Fig. 1, disposed below the weighing mechanism andsupported by the lower plate member 11.

As soon as 'the wires 2 have been delivered from the yokes 178, the weights 176 on the rearwardly extending portion of the balancing levers 175, will cause the said yokes to return to the position shown in Figs. 8

,and 6. They will then be ready to receive the subsequent-,wires dropped from the knotting mechanism. llnasmuch as the wires are of uniform cross section and length, this weighing mechanism will serve the purpose knetter head 110, Fig. 30, which recipro-l cates in the orifice 195 of the thiinble ortube 196, Figs. 12, 16 and 29, and carries said end .portion 157 with it. But the end portion 157 of the wire being disposed in a directiontransverse to the orifice 195, where the groove 158 carrying the wire enters the Said Orifice it bends the wir@ into the loop' 170,-best shown in Figs. 14 and 30, and forces the parallel disposed members of said wire to occupy the grooves 159 and 160 of the said head 110. The rotation of said head while inside said orifice 195, as indicated in Figs. 23, 211 andn2`6, naturally winds the bent looped portion of the wire around the straight unbeiit portion thereof as indicated, and the movement of said head 110 out of said orifice 195, naturally permits f posed grooves and a slot associated therewith and adapted to engage a wire; means provided with an orifice into and out of which said wire engaging means may move; means to mbve said wire engaging means into and out of said'orifice; and means to rotate said wire engaging means.
